Geographic Coordinate Data BaseGeographic Coordinate Data Base (GCDB) is an integrated network of survey records, horizontal control, and land descriptions, that together portray the Public Land Survey System (PLSS). The GCDB data is collected by the BLM offices to provide a high-quality framework for Geographic Information Systems (GIS). Township data downloads and other information are available for various states, including Oregon.

The Federal Geographic Data Committee coordinates the development of the National Spatial Data Infrastructure (NSDI). The NSDI encompasses policies, standards, and procedures for organizations to cooperatively produce and share geographic data. The 17 federal agencies that make up the FGDC are develop- ing the NSDI in cooperation with organizations from state, local and tribal governments, the academic community, and the private sector.

The Branch of Geographic Sciences, Oregon State Office, Bureau of Land Management, provides surveying, mapping, and GCDB data and support in the states of Oregon and Washington.
